Methods we use locally
The right method depends on soil conditions, depth of failure, and access on site. The engineer's design decides, these are the options on the table for Brighton properties.
| Method | Time on site | Best for in Brighton |
|---|---|---|
|
Beam and base
Reinforced concrete beams that spread the load. |
2 to 6 weeks | Variable ground, bay windows, redistributing loads. Common on bay windows and settled extensions through Lewes and Hove where loads need redistributing along a single elevation. |
|
Foam injection
Lightweight stabilisation that works to depth. |
1 day for most jobs | Slab re-levelling, void fill, conservatory bases. Useful for re-levelling slabs and floors in Hove and Bexhill-on-Sea, where access for excavation is tight and disruption must be kept low. |
|
Mass concrete
The traditional method, done properly. |
2 to 6 weeks per elevation | Shallow failures on traditional ground, insurance claims. Well-suited to traditional brick properties across Brighton, Eastbourne and Hastings where shallow bays can reach competent ground by hand. |
|
Mini piled
When the good ground is a long way down. |
1 to 3 weeks on site | Deep bearing layers, made-up ground, restricted access. The usual answer for deep clay or made-up ground around Brighton and Bexhill-on-Sea, and for rear-only access through the property. |
|
Resin injection
Targeted ground improvement, no excavation. |
1 day for most jobs | Granular soils, intact foundations, voids and density loss. Quick non-disruptive fix for shallow void filling and ground stabilisation across East Sussex, suited to lighter loads in Eastbourne and Lewes. |
|
Screw pile
Helical piles, no concrete cure time. |
2 to 5 days | Lighter loads, time-critical jobs, conservatories. Low-vibration option for terraces close to neighbours in Hastings and Crowborough, with quick installation and minimal spoil. |
